the discharge of material from the bucketV may be readily controlled.

The accompanying drawings'illustrate my invention.

Figure 1 is a side elevation of a dumping bucket embodying my invention;Fig. 2 an end elevation with the operating bail partially broken away. Y

In' the drawings 10 indicates a bucket or receptacle of any' desiredform having an open bottom. Arranged to close the open bottom are twosimilar doors 11 and 12 each of which comprises, in addition to thesuitably curved main or bottom plate, a pair of side plates 13, 13pivot-ed upon pins 14, 14, the outer ends of the pins being supported byplates 15 with the side plates 13, 13 lying between the ends of a plate15 and the adIi acent end (plate of the bucket 10. cure at 16 to eachend-plate 13 of door 11 is one end of a link 17 and pivotally secured at18 to each end plate 13 of the door 12 is a link 19. The links 17 and19, at each end of the bucket, are inclined toward each other and areconnected at 2() and 21 respectively to an o erating bail or lever22 onopposite sides o1P the pivot 23 of said lever.

lFor cheapness of manufacture I prefer to make each of` the links 17 and19 double and make the pivotal connections between said links and theconnected arts by means of short dpins passed througli the severalconnecte parts and held in place by means of cotter pins 24. Each pin 23has its outer end su orted by a bracket25, said lpin 2,3, as we as pins14, 14 being held in position by cotter pins, already described. Anyother means for forming the pivotal connections Specification of LettersPatent.

serial No. izaiaa and supports for the various parts may be as i readilyused'.

The adjacent portions of the bottoms 11 and 12 are substantiallystraight but at their outer edges said bottoms are curved slightlyupwardly and thel several pivotal supports and connections are arrangedsubstantially in the relations shown in Fig. 1 so that the doors, withany load applied thereto .within the bucket,'will be substantiallybalanced by the Weight of the operating bail 22 when said doors are inany of their various positions thus making it possible to readily openor 'close the doors, either entirely or partially,

under any load conditions which may exist, the arrangement of said partsbeing also such that the two doors will move synchronously in op ositedirections.

I c aim as my invention 1. The combination with an open-bottomedreceptacle, of a pair of closing doors therefor, each having u wardlyextending sides pivotally connecte to the receptacle, an operating bailpivoted to the receptacle, and a pair of links at each end of the recetacle, said links pivotally connected to the nail onopposite sides ofthe axis thereof andextended in opposite directions tov and pivotallyconnected with the sides of the doors. 2. The combination with anopen-bottomed receptacle, of a pair of closing doors therefor, eachhaving u wardly extending sides pivotally connectedp an operating bailpivoted to the receptacle, and a pair o links at each end of the recetacle, said links pivotally connected to the ail on opposite sides ofthe axis thereof and exto the receptacle,'

tended in op osite directions to and pivotally [in s.]
